The purpose of this project was to evaluate technology deployments on three arterial study corridors in Arizona. The corridors were evaluated based on criteria relating to such aspects as operations, maintenance, performance measurement, and cost. Field visits were conducted to inventory each corridor\u2019s system, and when available, the data obtained were used to quantify performance in terms of system functionality and system efficiency. A prototype spreadsheet was developed using multiple criteria decision analysis (MCDA) to score corridor deployments based on predefined criteria. It was found that communications technology and comprehensive Advanced Traffic Management System (ATMS) software contributed to the highest scores on the corridors evaluated. The project team recommended minimum and ideal technology configurations for signalized arterial corridors. It was also found that the Arizona Department of Transportation (ADOT) would benefit from improved ATMS software and from maintenance of a technology inventory.110
